Can b going down the rd and vehicle will die. Put in neutral and coast and will restart. Occasionally will have to pull off rd and sit for a min and it will restart. In warm weather it does it a lot. In cold weather it hardly does it at all. Have changed fuel filter. Also have had it hooked up to a machine and it shows nothing wrong. U can also b going down rd and floor it and it will not accelerate at all and will coast then die. Thinking fuel pump but no clue.
